  • Patent number: 9023458
    Abstract: In one aspect, methods of patterning of thin films of an ionotropic polymer (e.g., poly(acrylic acid)) are provided. These processes can create micron or sub-micron-scale patterns of ionotropic polymers such as cation crosslinked poly(acrylic acid) (CCL-PAA). In one embodiment, patterning may be performed within microfluidic channels by flowing a solution of crosslinking agent (e.g., metal cations such as Ag+, Ca2+, Pd2+, Al3+, La3+, and Ti4+) that can crosslink a portion of an ionotropic polymer in contact with the solution. In another embodiment, methods of patterning ionotropic polymers involve photolithography. Upon patterning a positive photoresist (e.g., diazonaphthoquinone-novolac resin) on a film of CCL-PAA, the exposed regions of CCL-PAA can be etched by an aqueous solution. Advantageously, the patterned, crosslinked polymer may also serve as both a reactant and a matrix for subsequent chemistry.

  • Patent number: 8742021
    Abstract: Ionomers and ionomer membranes, consisting of a non-fluorinated or partly fluorinated non-, partly or fully-aromatic main chain and a non- or partly-fluorinated side chain with ionic groups or their non-ionic precursors, have a positive impact on the proton conductivity of the ionomers. Various processes produce these polymeric proton conductors.

  • Patent number: 8686054
    Abstract: A new class of membranes for use in protective clothing. More specifically, the present invention relates to a polymer-polymer membrane with an ionic polymer located within the nanopores of a porous polymer host membrane. A method for making the polymer-polymer membranes involves filling porous polymers with ionic polymers. The porous polymers may be fabricated by a template synthesis which involves sorption. The ionic polymers may be filled in the nanopores of the porous polymer by plasma-induced graft copolymerization of the ionic polymer with the porous polymeric host membrane.

  • Publication number: 20140066529
    Abstract: Silica polyamine composites (SPC) made from silanized amorphous nano-porous silica gel and poly(allylamine) (BP-1) were functionalized with phosphorus acid using the Mannich reaction, resulting in a phosphonic acid modified composite (BPAP). Zirconium (IV) was immobilized on BPAP. Arsenate anions strongly adsorbed on the ZrBPAP composite in the pH range 2 to 8, while arsenite only adsorbed well at pH 10. Regeneration of the resin was carried out successfully for As(V) and As(III) using 2M-H2SO4. Four adsorption/desorption cycles were performed for As(V) at pH 4 without significant decrease in the uptake performance. ZrBPAP capture capacity and kinetics for arsenate were tested for longevity over 1000 cycles with only a marginal loss of performance.
